ROBERT H. ISBELL, OF NEW YORK, N. Y.

BUTTON.

SPECIFICATION forming part of Letters Patent No. 380,403, dated November 1'7, 1885.

Application filed February 9, 1885. Serial No. 155,371.

To all whom it may concern:

Be it known that 1, ROBERT H. IsBELL, of the city, county, and State of New York, have invented a new and useful Improvement in Buttons, of which the following is a specification.

My invention relates to the manufacture of buttons, the front or face of which is cloth or other desired material, and having the edge and body composed of vegetable ivory, horn, wood, or other suitable hard substance.

In order that my said invention may be more easily and clearly understood and more readily performed, I will give a full, clear, and exact description of the same, reference being bad to the accompanying drawings, and to the letters of reference marked thereon, similar letters indicating similar parts, making a part of this specification, in which- Figurel is a central vertical sectional view of a completed button. Fig. 2 is a central vertical sectional view showing the different parts of the button before the same have been pressed into position. Fig. 3 is a View showing the front of a completed button.

The body or main portion A of the button is made of vegetable ivory, horn, wood, or other suitable hard substance, and has in its front a circular recess, D, the sides of which fall outward toward the bottom, thus forming a dovetail, as shown in Figs. 1 and 2. Into this recess the cloth or other desired front of the button is fastened in the following manner, viz: Over the concave side of a circular concave piece of metal, 0, is stretched a cir- (No model.)

cular piece of the material of which it is desired to form the front of the button, slightly larger than C, and its edges are folded over the edge of and under 0. The same is then placed in D, as shown in Fig. 2, and a suitable pressure being applied upon them the metal 0 is flattened out, and the front B of the button is firmly secured under 0 and between its edge and the dovetail sides of the recess D. The same result can be obtained by using a circular corrugated piece of metal instead of C. By this means a button is made having a front of cloth, while the edges, which are most exposed to wear, are composed of a hard substance capable of withstanding the same.

I am aware of the English Patent No. 1,360'

of 1884., and the United States Patents Nos. 302,781 and 305,620, and make no claim to anything shown therein.

I claim as my invention and desire to secure by Letters Patent- In a button, a body formed of inflexible material, having a front opening provided with an undercut recess, a metallic disk of larger diameter than the outer opening of said recess andinclosed in the same, and a cloth face held tightly stretched over the face of the disk and inside the recess by the inflexible edges of the expanded disk which binds the cloth face against the sides or walls of the recess, substantially as described.
